System Cooling
Two 4-cm counter-rotating fans provide the cooling for the system. An additional (optional)
fan may be installed in the SC504 chassis Each fan unit is actually made up of two fans
joined back-to-back, which rotate in opposite directions. This counter-rotating action generates
exceptional airflow and is effective in dampening vibration levels. The chassis provides two
additional open fan housings, where an additional system fan may be added for optimal
cooling.
It is very important that the chassis top cover is installed for the cooling air to circulate properly
through the chassis and cool the components.
Installing Fans
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining fans
will ramp up to full speed. Replace any failed fan at your earliest convenience with the same
type and model (the system can continue to run with a failed fan).
One system fan is included in the system. Up to two additional (optional) fans may be installed
in the SC504 chassis.
